a is the front cross-spring, curved upward, as shown, the outer ends of which are coupled by means of links or rings to the forward ends of the side springs b, which have their curves placed downward, and to which is secured the axle d.

The springs c c are curved upward, as shown, and have their rear ends secured to the rear ends of the side springs b, while their forward ends extend inwardly in a diagonal or partially diagonal direction between said side springs, and are brought together or nearly together centrally between the forward ends of the springs 11, and under the center of the, cross or forward spring a;

- and they are secured to the spring a by a stirrup or loop, 6, which is, by preference,- so at tached as to be capable of a slight rocking movement, which adapts itto any depression given to one side or the other of the platform.

. complete and secure brace for the fifth-wheel k.

i is the hole through the bar f, through which the kin g-bolt passes.

This improved spring is strong, durable, and flexible, and readily adapts itself to the varied movements of the running-gear of the vehicle.
